This invention relates to a new system for the traction of vehiclesy ot any kind, and has essentially for its object a system of traction by means of which it is possible to increase V the force through the medium of the vehicles own Weight. By means of the traction system of this invention other advantages are obtainable which will be disclosed in the present descrip- 10 tion and will be made conspicuous in the claims hereunto appended. Y

In order that this invention may be clearly understood and readily put into practice, an example of the working arrangement is given in the accompanying drawings :--V y Figure 1 is a side elevation, partially in section, of a driving wheel in accordance with j the present invention. v

Figure 2 is a vertical transverse section of the same, and:

Figure 3 is an enlarged fragmentary horizontal detail sectional view.V

In al1 the gures mentioned, the same reference numbers indicate corresponding parts. In accordance with the present invention the driving axle 1 of the vehicle which is supported by its frame 2 either fixedly orV through the medium of springs, transmits the movement to a floating axle 3`to each end of which is firmly fitted the driving or pulling wheel 4, which in the present case is joined by spokes 6 to the tires 5. 'Ihe tires may be of any kind, either for road running or for running on rails and, Vif so desired, rubber tires orany other kind can be fitted.

As will be seen, the axleV 3 of the driving wheel is capable of forward and back movement in regard to the solid driving axle 01": the vehicle, and, consequently, the relative 0 positions of these two axles .can be varied vertically.

The axles 1 and 3 Aare connected by means of a rod 10, so that the distance between them is always maintained, the saidconnecting rod 5 'serving to transmit the weight ofthe vehicle from the axle 1 to the axle 3 and,-consequent ly, to the road. p The transmission of motion between axle 1 and axle 3 is eil'ected by means of a cog-Wheel "o 7 on the axle 1, which transmits the movement vvof the saidaxlel. through the medium?o'ia j l chain or similar arrangement 8" to a cog-` wheel 9. on the floating axle A3.

i The relation .of distancebetween 'the cog- Y' wheels 7 and 9'can be varied according tothe desire of increasing the force or velocity,

which is obvious to those wellversed in matters of this ln'nd.

It will be seen that'both the cogs and connecting rod are encased in a box V11 formed by the part 4 of the wheel and a cover 12, which enables them to be kept in a coat of oil or` grease. If it is desired, this cover 12 may be joined to the connecting rod 10.

` On the revolution of the axle 1, by reason f' of the resistance of the wheel 5, the connecting rod l0 tends to assume a slanting position, the weight of the vehicle assisting in carrying the said connecting rod toa verticalposition, through which the draught of the chain on the haulage side is increased. When the said force or resistance is increased as a result of any obstacle that may be encountered on the road, the wheel' increases thevtendency of the said connecting rod. to take up a slanting position in consequence of which the action of the weight of they vehicle is greater.

In order to obviate'the jolts whichas a consequence of these movements, may be produced by the axle 3, intermediate springs are fitted on opposite sides of the latter for the purpose of counteracting the said jolts, the springs to be of the type 13 shown in drawings made of metal, although rubber buiers may be substituted and which are fitted in y any convenient way to the body of the vehicle.

In accordance with this invention-the sys- Y be put into effect, I hereby declare that what I claim to be my own invention is 1. The combination of a traction wheel; a floating shaft carrying the same; a driving 5 shaft; resilient means active on the floating shaft to tension the same when displaced; means uniformly spacing the shafts from each other; and means for transmitting motion from one shaft tothe other.

2. The combination with a vehicle frame,

of a power shaft connected thereto; a floating, shaft superposed relative to the latter; opposed tensioning members supported in the frame and active against the floating shaft at opposite sides; driven connections between the shafts; and enclosure for the driven connections; and means spacing the shafts uniformly from each other.

Y In testimony whereof I affix my signature.
